It will be interesting to see how they play it. It's a little different in the past where the team could set their rotation by having them pitch in the 2nd to last series of the season so they are rested but not rusty going into the NLDS. But in this format, the Braves will have 6 days off between their last regular season game and first NLDS game due to the WC round.
In past years I'd think the 2nd to last series of the season is a bad time to play them because they'd probably set their rotation in that series and then rest people the final 3 games of the season. But in this format, maybe they rest starters the 2nd to last series and have their starters go in the final series of the season so they don't have like 11 days of between starts. Who knows, but either way I wouldn't rely on the Braves half assing it against us. It will still be a tough series.
The Brewers might be different. I'm assuming they'd want Burnes, Woodruff, Peralta to start in the WC round that is 10/3-10/5. If Counsell has the opportunity to set his rotation for that round and ideally give his guys a 5th day of rest before the playoffs, he'd ideally have them going the 27th, 28th, and 29th, meaning only 1 of them (probably Peralta) would go against the Cubs. But that's only if they've clinched the division in time to set that up.
